Benefits of technology

The present invention relates to a device, method, and computer program that allow for the creating and displaying of comments on video that is captured during movement. The invention addresses the problem of difficulty in identifying the location of a comment character string in relation to the video and provides a solution to display the comment in a way that is easily understood. This allows for users to provide commentary on the video with greater ease and accuracy. The technical effects of the invention include improved accuracy and efficiency in identifying and displaying comments on video, as well as improved user experience and ease of use.

Problems solved by technology

However, in the conventional technologies, there is a problem in that a comment corresponding to the location of video that is in the middle of reproduction is not displayable.
However, since the map is a bird's eye view, there is a possibility that it takes a time for acquiring the location of a commented site without enlarging a specific area or the like.

first embodiment

[0033]Configuration of Comment Creating-Displaying Device According to First Embodiment

[0034]The configuration of a comment creating-displaying device according to a first embodiment will be described with reference to FIG. 1. FIG. 1 is a functional block diagram that illustrates an example of the configuration of the comment creating-displaying device according to the first embodiment.

[0035]As illustrated in FIG. 1, a comment creating-displaying device 100 includes an input unit 101, a display unit 102, a storage unit 110, and a control unit 120. For example, the comment creating-displaying device 100 is used in a case where video (for example, an on-vehicle moving image), which is captured while a vehicle or the like is moving, is browsed. Video such as on-vehicle moving images is stored in a server device that is connected to the comment creating-displaying device 100 through a network, and a user selects and browses video from a plurality of video items.

[0036]The input unit 101 ...

second embodiment

[0077]In the first embodiment described above, the case has been described in which a comment for the location corresponding to video that is in the middle of reproduction is added. In a second embodiment, a case will be described in which the display position of a comment is set when the comment for the location corresponding to the video that is in the middle of reproduction is added.

[0078]More specifically, in the second embodiment, in a case where a comment is input, direction information is added by setting the display position of the comment displayed on the display screen. In addition, in the second embodiment, the display / non-display of the comment is controlled based on the added direction information. For example, even in a case where a comment for Mt. Fuji is input to video from Tokyo toward Shizuoka, Mt. Fuji is not projected on video from Shizuoka toward Tokyo, and accordingly, there is a case where it is undesirable to display the input comment even at the same locatio...

third embodiment

[0107]In the first embodiment described above, the case has been described in which comment character strings corresponding to comment coordinate values each having a distance between the positioning point of the positioning data of video that is in the middle of reproduction and the comment coordinate value to be a predetermined distance or less are added to the comment list. In a third embodiment, a case will be described in which a useful comment character string is added to a comment list with a high priority.

[0108]More specifically, in the third embodiment, in a case where a plurality of comment character strings to be displayed during the reproduction of video are present; there is a possibility that it is not preferable to display the plurality of comment character strings in the comment display area 21 at one time. Thus, comment character strings required to be displayed and comment character strings that may not be displayed are sorted out. In the sorting out of comment cha...

Abstract

A comment creating-displaying device includes: a comment storing unit that stores comment information in which a comment character string representing a character string displayed during reproduction of video captured during movement and a comment coordinate value representing coordinate information of a capture location at which the comment character string is displayed are associated with each other; a first acquisition unit that acquires positioning data that is information including the video, positioning time representing time when the capture location of the video is positioned, and a positioning point representing coordinate information of the capture location of the video; a reproduction control unit that controls reproduction of the acquired video; and a second acquisition unit that acquires the comment character string, which has a distance from the positioning point of the positioning data corresponding to the reproduction time of the video.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to and incorporates by reference the entire contents of Japanese Patent Application No. 2012-225037 filed in Japan on Oct. 10, 2012 and Japanese Patent Application No. 2012-225052 filed in Japan on Oct. 10, 2012.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a comment creating-displaying device, a method of creating and displaying a comment, and a comment creating and displaying program.[0004]2. Description of the Related Art[0005]In recent years, in accordance with the spread of terminals such as multi-function mobile phones (smartphones) each having a global positioning system (GPS) receiver built therein, various services using location information are provided. As one form of such services, there are services in which a comment is shared among users by displaying the comment, which is input by a user, relating to a specific position on a map.[000...
